Nasal Swabs for Sample Collection

I believe many people are very curious.

There is already a throat swab.

Why do you have to do a Nasal swab?

In the actual anti epidemic work scene, in fact, medical staff have a set of scientific judgment basis for collecting oropharyngeal swabs or nasopharyngeal swabs.

Because the nose swab only needs to expose the nose during the sampling process, the probability of exposure to the virus environment is low.

For high-risk people, such as asymptomatic infected persons, entry personnel or suspected people being isolated.

Nucleic acid detection with nasal swabs can reduce the infection risk of collectors, and the psychological acceptance of samplers.

That is, medical personnel, is also higher.

For the nucleic acid detection and screening carried out in the community, due to the more emphasis on rapid screening, the use of oropharyngeal swabs is more convenient and fast.

If discomfort or slight bleeding occurs during the collection of nasopharyngeal swabs, it is generally not treated.

After a period of time, the discomfort will disappear automatically.

If it is really uncomfortable, it can be properly cleaned with normal saline.

But do not wash too much, too much cleaning may bring more pollution.

Why is flocking swab used in nasal swab PCR test？

In order to improve the swab collection efficiency and meet the needs of end consumers for high-quality products.

Cell medical’s Flocked swab came into being.

Innovative jet implanted nylon fiber technology to maximize the sampling efficiency of the sampling swab.

The nylon fiber is vertically and evenly attached to the surface of the swab head, greatly increasing the collection and release efficiency of cell and virus samples.

Improve the analysis sensitivity, no sample residue, speed up the sample processing process, and the unique breakable design of ABS plastic rod.

It is applicable to the collection of cervical, nasopharynx, oral throat, forensic samples, virus, DNA and other samples.

◆ upright nylon fiber is like a soft brush, which can collect more specimens.

The capillary action between nylon fibers enhances the load of aqueous samples, and the samples are concentrated on the surface of the swab, which is easier to elute.

◆ it has outstanding sample collection and release ability, can quickly adsorb micro samples, and has high release aging rate. The increase of the number of target cells is helpful to improve the sensitivity of rapid diagnostic test.

◆ flocked swab has obvious advantages in nasopharyngeal sampling and microbial sampling, especially in the collection effect of virus and DNA.

◆ 100000 class purified environment, strict production process conditions, and production under ISO13485 quality control and product CE requirements. No DNase and RNase, no endotoxin, no cell inhibitor.

How do you use a flocked swab?

Nasal swab collection method.

(1) Wet the swab in normal saline.

(2) Measure the distance from nostril to ear root with a swab and mark with your fingers.

(3) Insert the swab into the nostril in the direction perpendicular to the nose (face) until the finger touches the nose, keep the swab in the nose for 15-30 seconds, and then rotate it gently for 3 times.

(4) Put the swab into the virus preservation solution or transport medium, break the swab rod and place it completely in the tube.

(5) Tighten the pipe cover, mark it, put it in a plastic bag and seal it.

(6) If it is necessary to collect from two nostrils, one swab should be used respectively.

(7) Store at 4 ° C (short-term storage).

What is the reason for choosing flocked swabs?

The flocked swab provides the advantages of swab heads with different shapes.

Its rapid adsorption capacity and excellent release efficiency provide protection for limited or trace DNA.

It is especially suitable for the extraction of outdoor field and contact exfoliated cells.

The sampling swab is composed of nylon short fiber velveteen wool head and medical grade ABS plastic rod.

The function of nylon short fiber is like a soft brush, which can effectively improve the collection of cell materials;

The capillary movement between fibers forms a strong hydraulic pressure, so as to absorb the liquid sample;

At the same time, the sample is close to the swab surface and easy to elute.

Mouth Swab VS Nasal Swab

Posted on 2021年9月28日2021年9月28日 by Dr. Lee

Mouth Swab VS Nasal Swab

Recently, COVID-19 is prevalent worldwide.

It is one of the most serious public health problems in the world.

The diagnosis of COVID-19 requires the combination of epidemiological history, clinical manifestations and laboratory examination, especially the examination of pathogenic pathogens.

It is an important basis for the diagnosis of New Coronavirus disease.

The diagnosis of COVID-19 needs to be checked by nucleic acid. If we can detect the virus, we can diagnose the disease.

The new crown vaccine is mainly used for the examination of the secretion. The most common method is to check the nasal swabs and mouth swabs.

The secretion of nasopharynx is used for nucleic acid detection. If there are positive findings, we can diagnose the disease.

There are certain differences between Mouth Swab VS Nasal Swab.

First, there are certain differences in the methods and parts adopted. Nasal swabs generally enter from the nasal cavity and take the secretions at the back of the nasopharynx, while pharyngeal swabs enter from the mouth to the throat and take local secretions for inspection, that is, the two enter in different ways.

Secondly, there are certain differences in the impact of nasal swabs and pharyngeal swabs on patients. Relatively speaking, nasal swabs are not easy to be accepted by patients. After entering the nasal cavity, they often need to enter a certain depth before they can effectively take samples. For patients, it may cause local discomfort. Pharyngeal swabs enter from the mouth and take secretions from the throat, It may also cause irritation such as nausea.

In addition, the positive rate of samples taken from pharyngeal swabs and nasal swabs is generally not much different, but for pharyngeal swabs, there may be some differences due to the influence of some oral factors.

However, at present, pharyngeal swabs are more widely used in clinic, and even some samples need to be collected together with pharyngeal swabs and nasal swabs, There is a certain possibility to improve the positive rate.

Oral Swab Stick

Posted on 2021年9月28日2022年3月22日 by Dr. Lee

Oral Swab Stick-Oropharyngeal sampling swab.

COVID-19 Oral Swab test is an important reference for diagnosis and evaluation of curative effect of new crown pneumonia.

Nucleic acid screening samples mainly come from deep cough sputum or pharyngeal swabs.

Pharyngeal swabs include nasopharyngeal swabs and oropharyngeal swabs.

The results of COVID-19 nucleic acid test are also useful.

What is the key to the collection of nucleic acid test specimens from pharyngeal swabs?

Whether collecting nasopharyngeal swabs or oropharyngeal swabs, the collection depth is the key.

For example, if the nasopharyngeal swabs are not collected deep in the nasal cavity, most of the cells that may be collected are virus-free cells, which may cause “false negative”.

What is the difference between Oral Swab Stick and Nasal Swab?

Pharyngeal division includes nasopharynx, oropharynx and laryngopharynx. The mucosa of the three is continuous and belongs to the area of upper respiratory tract. The sampling path of nasopharyngeal swab and oropharyngeal swab is different. Oral sampling is oropharyngeal swab and nasal sampling is nasopharyngeal swab.

What are the advantages of nasopharyngeal swabs?

It can stay in the pharynx for a long time in order to obtain more sufficient specimens; The exposure risk of the sampler is lower than that of the oropharyngeal swab, because the sampler can stand behind the patient’s side during sampling, and the patient is required to pull down the mask to expose only the nostrils and cover the mouth without looking directly at the patient’s mouth, and there is basically no pharyngeal reflex. A few patients may have sneezing reflex after sampling, and the patient can be covered with elbows or paper towels, And because the sampler is not directly in front of the patient, the exposure risk is quite low, so the psychological pressure of the sampler will not be so great.

Can a positive oral swab stick confirm COVID-19?

The novel coronavirus novel coronavirus infection can be diagnosed by the new swab positive guide for new coronavirus infection, but it does not necessarily indicate pneumonia.

After infection with COVID-19, the old person may show two different infections, including fever, dry cough, weakness, and asymptomatic infection.

Patients with positive nucleic acid test of new crown must be isolated and treated.

Only when nucleic acid is negative for more than 24 hours, body temperature is normal and pneumonia symptoms disappear can isolation be lifted according to the situation.

How to sample oropharyngeal swabs?

First collect the oropharynx, gently and repeatedly wipe it for more than 3 times, and then collect the depth of the throat wall for more than 3 times.

The whole process takes about a few seconds. It may be a little disgusting, but there won’t be too many reactions. It’s more acceptable.

According to the personal experience of colleagues: slightly disgusting, but completely acceptable

The site experienced the collection of oropharyngeal swabs. The whole sampling process is only a few seconds and there is almost no discomfort.

What is a Nasopharyngeal Swab?

Posted on 2021年9月23日2022年3月22日 by Dr. Lee

What is a Nasopharyngeal Swab?

COVID-19 Nucleic acid swab test is a very effective and effective measure to prevent and control the new crown pneumonia epidemic.

The upper respiratory tract of human body includes nasal cavity, pharynx and throat.

That is to say, if people are infected with COVID-19, they can extract the nucleic acid of the virus in the nasal cavity, pharynx and larynx in 96 hours.

Therefore, we usually sample these locations in the rapid detection of new crown nucleic acids.

How to collect a nasopharyngeal swab?

Nasal swab sampling process

The first step is to collect secretions.

First, the medical staff will use a pharyngeal swab to wipe the subject’s nasal cavity or throat tonsils to collect salivary secretions.

nasal swab collection method

The second step is to reserve samples.

After collecting the sample, immerse the nasopharyngeal swab in the preservation solution and screw on the tube cover to retain the sample.

The third step is to send samples for inspection.

Then, put the samples into clean sealed bags and send them to relevant parts for testing.

The fourth step is nucleic acid extraction.

Relevant departments will send the samples to the designated laboratory for nucleic acid extraction experiment.

Step 5: fluorescent PCR nasopharyngeal swab.

After collecting nasal samples, the experimenter uses fluorescent PCR to detect whether there is amplification reaction.

That is, to judge whether it is negative or positive.

Step 6:Finally, Receive test report.

Finally, according to the fluorescent PCR reaction results of nucleic acid detection, the nucleic acid detection vehicle inspection report is obtained, and I can query the results.

Sampling swab material

The sampling swab used for nasopharynx collection consists of a narrow rod made of a short plastic rod, one end of which is covered with an absorbent material. Such as cotton, polyester or flocked nylon.

The swab used for virus sampling should directly contact the sampling part.

The material of the sampling head is closely related to subsequent detection.

And the material requirements of virus sampling swab will be very high.

The virus sampling swab head shall be made of polyester (PE) synthetic fiber or artificial fiber.

Forbidden to use calcium alginate sponge or wooden swab (including bamboo stick).

However, calcium alginate and wood components can also absorb proteins after immersion in the preservation solution, and even inhibit the subsequent PCR reaction.

What are the advantages of using flocked sampling Nasopharyngeal swabs?

1. Flocked swabs provide better sampling.

Flocking swabs are a good choice for rapid diagnostic tests because they can better collect cells or organisms at the collection site and ensure the rapid release of the whole cell.

2. Enhanced diagnostic sensitivity.

Professional flocked technology turns each fiber into a velvet like swab, thus creating hundreds of thousands of contact points to better collect and release the collected samples.

Compared with non aggregated swabs, the increase in the number of target cells helps to improve the sensitivity of rapid diagnostic tests.

3. Rapid elution.

Their stable and reliable performance and excellent absorption and elution ability.

4. Easy handling and transportation.

What’s the use of a flocked nose swab？

Nasal swab detection is a kind of nucleic acid detection, which is used to detect the presence of viral nucleic acid in the body. So as to determine whether the human body infected with COVID-19.

Nasal swab detection requires collecting cells deep in the throat of the tested person and placing them in a Petri dish for observation. Because New Coronavirus is mainly transmitted through the respiratory tract,if the human body is infected with COVID-19, there will be a lot of viruses in the throat. Therefore, it is a more accurate way to detect the existence of COVID-19 by detecting the cells in the throat.

What is the method of mini nasal swab collection?

① Please keep the patient’s head still and remove the secretions on the surface of the anterior nostril;

② use a flocked swab or other tools to the distance from the nostril to the root of the ear and mark it with your fingers;

③ insert the swab gently and slowly through the nasal cavity;

④ swab until the finger mark or stay for several seconds after encountering resistance to absorb secretions; (generally stay for 15-30 seconds, and then rotate gently for 3 times);

⑤ gently rotate the swab and put it into the virus sampling tube (transport medium); Break the swab tail rod along the breaking point and place it completely in the tube. Tighten the pipe cover.

⑥ If you need to collect from two nostrils, you should use another swab.

⑦ Send to the inspection room for inspection as soon as possible.

⑧ Note the information of the collected person to avoid confusion.
